TASK 4

After normalization, Using Ms Access 2007 I created the database below with the following tables.

Database tables and the populated data:

PM – Project Manager, D – Developer, PR – Principal Researcher

TASK 5

5a) The SQL statement

SELECT Projectsundertaken.ProjectId, Projects.ProjectName, Academics.AcademicName, Projectsundertaken.AcademicRole, Projectsundertaken.StartDate, Projectsundertaken.EndTime, Projectsundertaken.Status

FROM Projects RIGHT JOIN (Academics RIGHT JOIN Projectsundertaken ON Academics.AcademicId = Projectsundertaken.AcademicId) ON Projects.ProjectId = Projectsundertaken.ProjectId

WHERE (((Projectsundertaken.Status)="Incomplete"));

Results of the SQL statement

5b) The SQL statement

SELECT Projectsundertaken.ProjectId, Projects.ProjectName, Academics.AcademicName, Projectsundertaken.AcademicRole, Projectsundertaken.AcademicTime, Projectsundertaken.StartDate, Projectsundertaken.EndTime

FROM Projects RIGHT JOIN (Academics RIGHT JOIN Projectsundertaken ON Academics.AcademicId = Projectsundertaken.AcademicId) ON Projects.ProjectId = Projectsundertaken.ProjectId

WHERE (((Projectsundertaken.AcademicRole)="PM"));

Output of the SQL Statement

Database assumptions

Each table to be edited has a one column primary key field which is an auto-incremented

integer field. It is possible to manually override this assumption, but it will require some

hand coding by the developer.

Tables have one primary key and foreign key.

Tables have relationships where referential integrity has been enforced.

There are no duplicate records in the database.

Whenever a field is updated a related record will be automatically updated.

The tables have the same layout and every field has been set to its proper data type will full

validation and verification.

Validation rules have been defined

Alternative approaches which could have been used in design, analyzing and implementing the

database.

The approaches which I could have used include DSD, PSD, Flow charts, Pseudo code and UML

(Unified Modeling Language) which have quite a number of advantages to offer in the development

of programs and they are as follows:

Graphical hence easy to understand

Easy to write or present

The UML development tool allows code to be exported.

Offers a ready made modeling language which helps developers to communicate.

The language is graphical and capable of expressing ideas.

It enables the modeling of systems and software using object oriented concepts.

It is also independent of programming language and development process.

Provides a formal basis of understanding the modeling language.

It supports higher level development such as collaborations, frameworks, patterns and

components.

Provides a means of extending the core concepts of a language

A standard model means easier communication between development teams

Provides a method for systems analysts to check that the program will achieve its goal.

TASK 5 NET

AIM

To create a report describing the network recommendations.

In this recommendation report, I compares several models of laptop against specific requirements

and then recommends one.

Introduction

This report gives an overview of why it is crucial for the organization to set up a network. If

the organization set up a network this will bring itself with other advantages and benefits to

the organization which includes the following:

Increased Communication Capabilities

Networks provide several different collaboration tools that can be used to

communicate between network users. Online collaboration tools include e-mail,

forums and chats, voice and video, and instant messaging.

Avoid File Duplication and Corruption

A server manages network resources. Servers store data and share it with users on a

network. Confidential or sensitive data can be protected and shared with the users

who have permission to access that data. Document tracking software can be used to

prevent users from overwriting files, or changing files that others are accessing at the

same time.

Lower Cost Licensing

Application licensing can be expensive for individual computers. Many software

vendors offer site licenses for networks, which can dramatically reduce the cost of

software. The site license allows a group of people or an entire organization to use the

application for a single fee.

Centralized Administration

Centralized administration reduces the number of people needed to manage the

devices and data on the network, reducing time and cost to the company. Individual

network users do not need to manage their own data and devices. One administrator

can control the data, devices, and permissions of users on the network. Backing up

data is easier because the data is stored in a central location.

Conclusion

Having taken into account the position of the organization I have concluded that the

organization needs this network since this will assist the organization in that computers which

are connected through a network can share resources as hard drives, printers, scanners etc

with each other, information, an connect all the computers which are connected through a

network to the internet by using a single line. So it means that you can save the connection

cost for each computer but you internet connection must be fast.
